After 4 years, Mercedes is making ready to improve the EVA2 platform utilized in EQE/EQS. Referred to as EVA2M, the brand new platform will obtain 800V know-how and the eATS 2.0 Drive propulsion system from the MMA platform.
Greater than a month in the past, we wrote that Mercedes is having issues with gross sales of the EQE/EQS and its SUV derivatives in China and the USA. One of many issues is that Mercedes’ luxurious electrical fashions are primarily based on a platform with 400V know-how, whereas cheaper rivals just like the Kia Ev6 and Hyundai Ioniq 5/6 have 800V platforms and bi-directional charging. Likewise, direct rival Porsche Taycan makes use of an 800V platform, which helps for shorter charging occasions, and a rear-mounted motor mated to a two-speed gearbox.
That’s why Mercedes reacted shortly, and the German press introduced that Mercedes will improve the EVA2 platform that will probably be used from 2025 within the facelifted EQE/EQS fashions.
EVA2M platform with 800V know-how, eATS 2.0 motors with scalable size and SiC inverter
Thus, the EVA2M platform will obtain from its smaller sibling MMA (Mercedes Modular Structure) the eATS 2.0 propulsion system with oil-cooled, everlasting magnet synchronous electrical motors with scalable size and silicon carbide inverter for sooner and fewer switching loss between DC and AC. The motors may also be capable of be coupled with a two-speed gearbox.
Due to the scalable size, the motors will be tailored for a variety of energy and torque. The brand new eATS 2.0 propulsion system may also be out there for the MB.EA platform.
Thus, within the close to future, Mercedes will depend on three electrical platforms:– MMA designed as Electrical First, which might additionally assist typical propulsion, meant for the brand new era of CLA, EQA/GLA, and EQB/GLB compact fashions.– MB.EA for the longer term electrical Mercedes C-Class and electrical GLC. At a later stage, the MB.EA platform may also be used for the following era EQE/EQS.– EVA2M, the upgraded model of the EVA2 that will probably be used for the EQE/EQS facelift and EQE SUV/EQS SUV.
